The talk went on while Beany whittled and pried away industriously at the table edge. He found a crack in the wood and pried his knife blade into that. The blade entered in a tantalizing manner, slipped smoothly along, then struck metal. Beany pushed. Porky, who was watching, came closer and peered down the crack. Beany pushed harder, pushed as hard as he could, and suddenly felt himself flung off the table as the big top flew up and hurled him aside.

Powerful springs had opened the two heavy slabs of oak that formed the table. Two pieces now stood open like a pair of doors and within lay a long, flat box which completely filled the space. The box was of iron, heavily barred and padlocked. Four soldiers pried it from its place and, escorted by the whole party, it was carried to General Pershing, still working at his desk.

Once more the boys had unearthed a mystery.

CHAPTER VIII

THE CELLAR'S SECRET

Porky and Beany were too tired to care what happened next and, taking quick advantage of a brief smile and nod of dismissal from the General, they made their way to their quarters and soon were as sound asleep as though they were lying on the softest down. They slept and slept, losing all track of time, and by the General's orders were undisturbed. When they finally woke, really wide awake, they found that a whole day and a night had passed since the early dawn when they had staggered off to bed.

They woke at the same instant, as was their habit, and sitting bolt upright, stared unblinkingly at the young officer sitting at the window writing.

"Morning, Lieutenant," said Porky, rubbing his eyes.

"What's the time, sir?" said Beany, looking curiously at his wrist watch.

"Yours stopped too?" asked Porky. "Mine has. Funny!"
